The electrification of ships and, particularly, of their propulsion is an area of intense research nowadays. A very appealing option that allows partial electrification of ship propulsion system is the use of shaft electric machines. Moreover, power dispatch is implemented in ships by using simplistic methods, in contrast to continental power systems where sophisticated optimal power dispatch methods...
Nowadays the propulsion electrification of ships is under intensive research. During this course, a very attractive option is the use of shaft electric machines, which is an intermediate step between the classic ship configuration and the all-electric one. However, two problems arise: (1) power dispatch should be carried out based on the Lagrange method or dynamic models, instead of simplistic methods...
In the following investigation the modeling of the complete electromechanical system of a doubly fed induction machine is discussed for power production/electric propulsion purposes, when being incorporated as a shaft generator into a ship's system. When the doubly fed induction machine serves as a power production machine, contributes to lower emission of CO2 and fuel saving since its capable of...
